Web-Based Spatial Data Infrastructure (SDI) to Implement and Monitor Nonpoint Source (NPS) Pollution Management in the Imperial Valley, California University of Redlands The Redlands Institute Serene Ong
Project Objectives and Process Presentation Overview Review GIS Database Review web-based tools & demo
Project Goals Support SWRCB, RWQCB, IID and ICFB for sediment TMDL implementation and compliance. Provide better access to water quality and farm practices data. Develop GIS database and web map application, custom query and report tools Anticipated Outcomes More efficient use of existing information Increased use of water monitoring and related data for TMDL management/research Recommended standards for formatting and reporting water quality and agricultural practices data
Stakeholders State Water Resources Control Board (SWRCB) Regional Water Quality Control Board (RWQCB) Imperial Irrigation District (IID) Imperial County Farm Bureau (ICFB) Communities and wildlife around Imperial Valley and Salton Sea

The Data
GIS Features Canals (inflow) Gates (entry point) Hydrology Features Drains (outflow) Tailwater Box (exit point) Schema based on NHD Compilation of IID and NHD linework and attributes Flow direction assigned Waiting on updated features from IID
Collection of plots monitored by a single R7 water quality monitoring station Drainsheds
Agricultural Practice Information Reported by farmers to Imperial County Farm Bureau under the ICFB Voluntary TMDL Compliance Program Owner & operator information Best Management Practices (BMPs) Crop types NPS problems Site conditions Data is maintained by the Farm Bureau and delivered to the Regional Board as a.csv file Schema (such as column headings) are often changed year-to-year For more information on the TMDL Compliance Program please visit http://www.ivtmdl.com/

The System ---------------------- Web-based GIS and reporting tools
IVSDI Website and System Designed to be a distributed service-oriented architecture leveraging existing services and standards where possible. Mapping application developed using JavaScript REST API for ArcGIS Server Local GIS and tabular data stored in ArcSDE 9.3 on SQL Server 2008 http://www.spatial.redlands.edu/ivsdi *This application is still currently under development
A little bit about web services A web service is an Application Programming Interface (API) that can be accessed over the internet. Web Service XML, JSON, etc Generally communicate over HTTP where a client (website or other) makes a request and the service returns a response in a format that may be easily parsed (xml, json, etc) by the application http://maps.google.com/maps/geo?q=73-720 Fred Waring Drive Palm Desert, CA 92260&output=xml&key=ABQIAAAAc73SoWFy

Agricultural Practice Report Uploader The Report Uploader allows authenticated R7 users to upload the latest Farm Bureau Report files to the system
Agricultural Practice Report Uploader The Report Uploader allows authenticated R7 users to upload the latest Farm Bureau Report files to the system The tool enforces the current standard by: 1) Checking missing, misnamed, or extra columns in the file Allows you to select the appropriate action for the error (ignore or add)
Agricultural Practice Report Uploader The Report Uploader allows authenticated R7 users to upload the latest Farm Bureau Report files to the system The tool enforces the current standard by: 1) Checking missing, misnamed, or extra columns in the file 2) Checking for invalid entries such as duplicates, empty values, invalid values, etc Allows you to fix errors directly on the page or download a new Excel file to correct
Potential Next Steps ----------------------
Since we are using data from a national data source, you can see and report on any water quality monitoring station in the state. Statewide Water Quality Sites
Potential State Watershed Site Potential State Watershed site
